The ability to query a symbol table for a custom apex class is great, but can we obtain this information for standard classes? I have tried things like...
SELECT SymbolTable FROM ApexClass WHERE Name = 'PageReference'
...but this doesn't work since only custom Apex Classes are stored in the ApexClass table. Right now i'm thinking about crawling the documentation to obtain a list of static and instance methods, class-by-class, but im wondering if this data is already available somewhere or can be obtained through API calls?
